Only a

C
Only c

D
Only b and c

Solution

A glomerulus is a network (as a tuft) of capillaries located at the beginning of a nephron in the kidney. It serves as the first stage in the filtering process of the blood carried out by the nephron in its formation of urine. The glomerulus is surrounded by a cup-like sac known as Bowman's capsule.

Waste products are stored as ________ in old xylem plants.

A
sucrose

B
glucose

C
resins

D
water

Question 4
1 / -0

According to ten percent law, only 10% of the energy is transferred to the next trophic level in a food chain. This law was proposed by

A
Frank Edwin

B
Raymond Lindeman

C
Henry Gleason

D
Arthur Tansley

Solution

In 1942, Lindeman put forth the famous ten percent law for the transfer of energy from one trophic level to another in a food chain.
Question 5
1 / -0

Which of the following organisms will most likely be affected by egg shell thinning by DDT?

A
Tortoise

B
Crocodile

C
Bald eagle

D
Electric rays

Solution

In birds, the accumulation of DDT leads to the thinning of egg shells, thereby causing premature deaths of the embryos. Since bald eagle is a bird, it is most likely to be affected by DDT.
Question 6
1 / -0

If the roots of px² - (p + q)x + q = 0 are equal, then

A
2p = q

B
p = 2q

C
p = q

D
None of these

Solution

For equal roots, Discriminant, D = 0

[-(p + q)]² - 4pq = 0

(p + q)² - 4pq = 0

or, (p - q)² = 0

or, p = q
Question 7
1 / -0

A company increases its sale each week by £400. If the company made a sale of £1400 in the 1^st week, then what will be its sale in the 15^th week?

A
£6000

B
£6500

C
£7000

D
£7500

Solution

Common Difference, d = 400

First Term, a = 1400

Number of terms, n = 15

Sale in the 15^th week = a + (n - 1)d

= 1400 + (15 – 1)400

= 1400 + 5600 = £7000
Question 8
1 / -0

If sin x = cos² x, then the value of cos²x (1 + cos²x) will be

A
1

B
0

C
2

D
-1

Solution

cos²x (1 + cos²x)

= sin x (1 + sin x)

∵ (sin x = cos²x)

= sin x + sin² x

= cos² x + sin² x

∵ (sin x = cos²x)

= 1
